Trying to find the value of a certain term in a geometric sequence? Use the formula for finding the nth term in a geometric sequence to write a rule. Then use that rule to find the value of each term you want! This tutorial takes you through it step-by-step.
When you're looking at a sequence, each value in that sequence is called a term. This tutorial explains the definition of the term of a sequence. Take a look!
Consecutive numbers are numbers in counting order. They tend to come up in words problems. Take a look at this tutorial to learn all about consecutive numbers!
Plugging variables into an expression is essential for solving many algebra problems. See how to plug in variable values by watching this tutorial.
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
You can't go through algebra without learning about functions. This tutorial shows you a great approach to thinking about functions! Learn the definition of a function and see the different ways functions can be represented. Take a look!
Trying to find the value of a certain term in a geometric sequence? Don't want to go through the terms one-by-one to find the one you want? Use the formula to find the nth term in a geometric sequence! This tutorial shows you how find that formula!
You have a pattern in your sequence. Great! Think it might be an arithmetic or geometric sequence? If the sequence has a common difference, it's arithmetic. If it's got a common ratio, you can bet it's geometric. Practice identifying both of these sequences by watching this tutorial!
